With the development of my country's industry, the appearance processing requirements of various industries are getting higher and higher. In the metal surface treatment, the coating methods currently on the market mainly include electrophoresis and electroplating. So what is the difference between electrophoresis and electroplating? What are the advantages and disadvantages?
First of all, let's first explain what is electrophoresis and what is electroplating. Electrophoresis is a process in which another resin ion deposits on the surface of the metal. A phenomenon in which charged particles (ions) in a solution move in an electric field. Electroplating is the process of plating a layer of other metals or alloys on the surface of certain metals using the principle of electrolysis.
1. Function
What are the differences between electrophoresis and electroplating in their functions?
Electroplating is the process of using electrolysis to attach a metal film to the surface of metal or other materials, so as to avoid metal oxidation (such as rust) and improve wear resistance, conductivity, light reflection, and corrosion resistance (copper sulfate Etc.) and enhance the beauty and other effects. Electroplating has a metallic texture.
While electrophoresis is only a high imitation plating, there is still a certain gap in performance and color. Electrophoresis is difficult to make electroplated metal texture.
However: in terms of the uniformity of the paint film, the film thickness of the electrophoretic paint coating is uniform at high and low potentials, while the high and low potential coatings of the electroplating layer are not uniform.
Electrophoresis is also more advantageous in the masking of paint film. Electrophoretic coating can completely cover hidden places, such as inner walls and recesses; while electroplating generally cannot deepen the hidden places.
Electrophoresis can only be applied to conductive metal surfaces; in addition to metal surfaces, electroplating can also be electroplated on specially treated plastics.
2. Cost
Electroplating is a layer of metal, while electrophoresis is coated with a layer of resin. Compared with electroplating, electrophoresis is simpler and easier to operate. So in terms of cost, there is a big difference. Electrophoresis is much cheaper than electroplating.
Three, environmental protection
Electrophoretic paint uses water as the solvent, with less waste and less environmental pollution.
Electroplating wastewater contains heavy metal ions such as chromium, cadmium, nickel, silver, and cyanide, which are prone to pollution.
